Brick machine pallet without steel edges bends under the weight of a long curbstone. That bending creates tension at the bottom of the wet stone. When the curbstone is demolded, the tension releases as hairline cracks. Those cracks grow during curing or after installation, and the product fails. Steel edges on two long sides eliminate this bending. The pallet stays perfectly flat, and the curbstone remains crack‑free. Therefore, any brick machine pallet used for curbstone production must have steel edges.
Block machine pallet faces the same problem when producing long curbstones. Even if your machine is designed for blocks, the pallet will bow under concentrated load. Steel edges on the two long sides prevent this bowing. A block machine pallet with steel reinforcement works equally well for curbstones and standard blocks. No bending means no cracked products.
GMT pallet made of 50% glass fiber offers excellent flexibility. Under heavy curbstone load, a standard GMT pallet bends. That bending cracks your product. Steel edges stop the bend. The pallet remains flat during pressing, and the curbstone comes out intact. For curbstone production, steel edges are not optional – they are required.
Fiberglass pallet with 0.55% ultra‑low water absorption already resists moisture well. However, curbstone weight is a different challenge. Without steel reinforcement, even a high‑quality fiberglass pallet will bend under the concentrated load of a long stone. Adding steel edges along the two long sides changes the behavior completely. The composite structure – glass fiber core plus steel profile – withstands the load without bending. That is why we require steel edges for all pallets used in curbstone production.
Pallet for brick machine shares the same physics. When you press a long curbstone, the middle of the pallet wants to dip. That dip cracks your product. Adding steel edges on the two long sides stops the dip. This simple reinforcement transforms any pallet for brick machine into a high‑performance tool for curbstones.
Steel-edge GMT pallet of this design lasts over 10 years, which is 3–5 times longer than standard pallets. The steel protects the core from edge impact and moisture ingress. The 50% glass fiber content provides the ideal stiffness‑to‑flexibility ratio. Not too rigid, not too soft. This combination directly reduces curbstone cracking because the pallet does not bow under load.
For high‑temperature curing (>90°C) , a standard GMT pallet may bend temporarily. Once it returns to normal temperature, it goes back to its original flat shape and can be used again. Steel edges are not mandatory for high‑temperature curing alone. However, if you are producing curbstones and also using high‑temperature curing, steel edges help reduce bending during the hot cycles.
